SPECIFICATION 'forming pari: of Letters Patent No. 363,4Q6, dated May 2.4, 1887.-.

Application tiled November 20, 18H6. Serial No. 210,133. (No model.)

To all whom, it 71u07/ concern.:

Beit known that we, LEVI J. WING, ofthe city, county, and State of New York, and THE- RON A. RICHARDS, of Brooklyn, county of Kings, and State olNew York, have invented certain new and useful Improvements in Oscillating Steam-Engines, of which the following is a specification.

This invention relates to. improvements iu 1o oscillating steam-engines, by which they are adapted to move small machinery oi'all kinds, such as Ventilating-fans, propellers for yachts, lathes, dynamos, sewing-machines, Src., hut which may also be used for heavy work. The i5 engine may be constructed with two or more cylinders. Forordiuarylight-runningmachinerytwo cylinders will he sufiicient, while for heavy work threeor more cylinders can be used.v The engine works without strain, noise, 2O or vibration, and has the advantage of simplicity, compactness, ease of application, and comparatively small cost of construction and maintenance.

The invention consists ofa supporti ugframe, z5 the center of which is provided with a journalloearing for the shaft to be driven, while the .ends ot' the supporting-frame are made ringshaped to receive the steamchests and the bearings for the pivots Of the oscillating steamcylinders. Each cylinder is provided with a disk-shaped face that fits tightly to the face of the steam-chest, so as to Vform close contact,to prevent any leakage of steam. The ports of the steam-chest supply and exhaust the steam to and from the port of the cylinder. The pistons are pivoted to a crank-pin of the shalt to be driven, so that by the alternating reci procating action of the pistons,in connection with the oscillations of the cylinders,continuous ro- 4o` tary motion is imparted to the shaft.

In the accompanying drawings, Figurel represents a top view, partly in horizontal section,of our improved oscillating steam-engine, shown as applied to a Ventilating-fan. Fig. 2 is a front elevation of the same with parts broken away to show one of the steam-chests. Fig. 3 is-a side view of one-half of the supporting-frame, and Fig. 4t is a rear view of one of the oscillating cylinders.

Similar letters ot' reference indicate correspending parts.

Referring to thc drawings,'A represents a tixed su pporting-l'rame, at the center' of which isarrauged a journal-hearing, c, for the shaft to be driven, while the ends of the frame A are provided with ring-shaped hearings a', which serve to support centrally-perforated stealu chests B, that form the' bearings B for the pivots C ot' two or more oscillating cylinders, D. The combinel steam-chests D and 6o pivot-bearings B are rigidly attached to the riug-shapediends a of the frame A by fastening-screws b b. The pivots C pass through the bearings B,and are attached to the hack of the frame A by fastening screw-nuts- (Z and washers d', said screw-nuts being applied to the threaded rear ends of the pivots, as shown in Fig. l.

The steam-chests B are provided with diskshaped faces B2, which are smoothly turned oii, 7o so as to form contact with the smooth diskshaped faces D of the cylinders D. The steam-chests B are provided with steam-admission ports e and exhaust-ports e', which are connected, respectively, with the steam in- 7 5 let and outlet pipes c2 e", as shown in Fig. 2.

A suitable two-way cock (not shown in the drawings) may be arranged in connection with the steam inlet and outlet pipes, so vas to permit the reversing of the engine and supplythe So steam to the former exhaust-porno', while exhausting through the former admission-port, e.

Each cylinder D is provided with a port, o, which registers with the port-s e c' of the steamchest B. The oscillating cylinders D are pro- S 5 vided at their closed ends with small openings closed by petcoeks f, through which the water ofeondensation is discharged from time to time.

At their opposite ends the cylinders D are provided with stuiiing-boXes f for the piston- 9o rods E, which piston-rods also perform the functions of pistons. The inner ends of the cylinders D are somewhat enlarged, so that the steam will play entirely around the inner ends of the pistons, while the remaining parts of the pistons are tightly itted into the contracted portions of the cylinders. The outer ends of the piston-rods E are pivoted to a crank-piu, g, of a disk, g', that is attached to the end of a shaft, F, which is supported in roo the center hearing, a, of the frame A, and to which motion is to he imparted by the oscillating` steam-cylinders D and reciprocating pistons E. Vhen steam is supplied to one cylinder, the other cylinder exhausts, so that the piston of the same can recede, while when the steam in the irst cylinder exhausts live steam is supplied to the second cylinder, and so on alternately, whereby an alternating oscillatory motion is imparted to the stea1n-cylinders and a reciprocating motion to the pistons, which latter impart a continuous rotary motion to the shaft F. The cranlrpin is passed over its dead-points by the momentum imparted to theV fan, fly-wheel, or other article located ou the shaft F, so that thc regular motion of the cylinders is kept up.

A small and compact motor for driving ventilating-fans and for other purposes is thus obtained, which motor can be arranged close to and as a part of the machine to be driven.

Having thus described our invention, we`

2. The combination of a supporting-frame having a central bearing for the shaft to be driven and ringshaped end bearings, steamchests fastened to said cnd bearings and provided with ports, oscillating steam-cylinders having pivots passing through said steamchests and provided With ports registering with the ports ot' the steam-chests, pistons reciprocating in said cylinders, and a transmittingshaft having a crank-pin connected to the outer ends of the pistons, substantially as set forth.

3. The combination of a supporting-frame having a center bearing and ring-shaped end bearings, steam-chests attached to said end bearings and provided with diskshaped faces and ports, steam-cylinders having faces fitted to the faces of the steam-chests and ports registering with the ports ofthe steam-chests, pistons reciprocating in said cylinders, and a transmitting-shaft supported in the center bearing and connected by a crank-pin to the outer ends of thc. pistons, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing Witnesses.
